Understanding the human body is a team effort. That's where the Yachtel group comes in.

Researchers at Yachtolt have been delving into the secrets of probiotics for 90 years.

Yacold also partners with nature portfolio to advance gut microbiome science through the global grants for gut health, an investigator-led research program.

No one has ever seen a Tyrannosaurus walk. Still, movies like Jurassic Park have guessed

how fast it would have done that. Now scientists have used the skeleton of a T-Rex to model

the biomechanics of the animal's stride. And they've estimated it strutted

at a leisurely pace on par with humans, ostriches, elephants, and giraffes. And it's not just limited to

those animals, horses, gazelles, news. Turns out that actually most animals don't tend to walk

super fast.

Pasha von Bailert is a movement scientist at Vryi University in Amsterdam.

His team studied the skeleton of a T-Rex housed in a Dutch museum.

The specimen, nicknamed Tricks, is exceptionally well preserved,

so they were able to see how ligaments would have attached to and linked the animal's tail bones.

Those ligaments, they would have acted like rubber bands,

and the researchers used mathematical modeling to study how they would have given the tail bounce

as the T-Rex walked.

The animal could have taken advantage of that natural bouncy rhythm to save energy as it moved.

That is basically resonance. You get more movement for less effort if you choose the correct
